When any of the four predefined throttling types are selected the Traffic Smoothing fields display.

Traffic Smoothing reduces the appearance of framedrop on the LAN client by smoothing traffic

from the NVR. Traffic Smoothing can be configured for both the client and the stream, it is entered

in Mbps and its default values for each of the four predefined bandwidth priorities will appear as

300 Mbps for the client and 75 Mbps for the stream, these figures can be edited to match the

capabilities of your network and your client host (client NIC and performance), as this feature

addresses issues with poor performance network cards on victor client.

Note

The Traffic Smoothing function is carried out separately from the four transcoded streams of video

and can reduce the NVR’s performance.

When Preserve Framerate, Preserve Resolution and Allow any throttle type are selected the WAN

and LAN bitrate cap dropdowns display.

Note

A bitrate cap limits the amount of streaming data (i.e. video) leaving the NVR to remote clients or

clients connected using VPN. The WAN bitrate cap cannot exceed the LAN bitrate cap.

The dropdown menus provide a list of predefined values which you can choose from. Alternatively

a custom value can be entered and there is no minimum entry value. This allows experienced

users to customise their WAN and LAN Bitrate Caps to best utilise their networks capabilities.

Note

If the LAN or WAN bitrate cap is set to a value which is less than the Traffic Smoothing value,

Traffic Smoothing will have no affect on the transmitted stream as it will adhere primarily to the

bitrate cap. It is recommended that Traffic Smoothing is set to a value less than or equal to the

LAN and WAN bitrate caps.



Usually WAN connections have lower bandwidth than

LAN connections, if the WAN bandwidth is

less than the default value of 150 Mbps Traffic Smoothing will have little to no effect.

When Preserve Framerate and Allow any throttle type are selected the Transcode Limit dropdown

also displays. This allows you to limit the number of transcoded streams between 1 and 4 to best

suit your CPU’s capabilities.

Traffic Smoothing Only

Allows the ability to pace the traffic leaving the NVR to individual clients without incurring

framedrop or transcode. This smooths bursts of traffic which may cause issues for some consumer

grade NICs consuming this data.
